SEALABLE FOOD CONTAINER David Wendell Hughes, Phoenix, Arlz. Application May 24, 1950, Serial No. 163,929

' 1 Claim.

This invention relates to lunch baskets.

It is an object of the present invention to provide in a lunch basket a Thermos type of container adapted to contain bulk food and to keep it at its initial temperature. I

It is another object of the present invention to provide a Thermos receptacle for lunch baskets adapted to fit the bottom of the same intermediate the length thereof and which has means attached to the same to prevent thesliding of the receptacle in the lunch basket, and wherein the spacing member may be 'removedfrom the receptacle at times when the receptacle is taken from the lunch basket.

Other objects of the present invention are to provide a Thermos receptacle having a wide open top which is of simple construction, inexpensive to manufacture, adapted to readily fit within the lunch basket, compact, has a minimum number of parts and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a perspective view of a lunch basket having a bottom part and a top part and having the Thermos receptacle embodying the features of the present invention.

Fig. 2 is a longitudinal sectional view taken on line 2-2 of Fig.1.

Fig. 3 is a perspective view of the receptacle removed from the lunch basket and looking upon the spacing bar.

Fig. 3a is a fragmentary perspective view of the cover.

Fig. 4 is a perspective view of a modified form of receptacle, the same being of cylindrical shape and having a screw cover.

Fig. 5 is a fragmentary sectional view of a v modified form of receptacle.

Referring now to the figures, l6 represents a bottom part of a lunch basket to which is pivoted a cover member ll of sufiicient depth as to receive and retain an ordinary Thermos bottle [2. This bottle is held in place by a clasp member l3. The bottle has the usual screw cap cover Within the bottom part Ill is a Thermos receptacle l5 having a cover part It adapted to be secured by spring clips l1 and I8 on the receptacle.

The receptacle further includes an inner glass tumbler or vessel l9 which rests upon the insulating piece 2| in the bottom of a metal receptacle 22. Surrounding the vessel i9 is an air space or vacuum 23. A sealing ring 24 is provided beneath the latch 25 of the outer casing 22.

The cover l6 has a flange 26, the under face of which rests against .seal 24. The under face of the flange 26 engages with a second sealing ring 21 which rests on the top of the inwardly bent flange 25 of the metal receptacle. The

cover IE is made of glass and is held in place upon the seal 21 .by the spring clips I7 and I8 secured to the outer faces of the sides of the metal shell.

In order to keep the container in spaced relationship with respect to the ends of the bottom l0, one side of the shell 23 is provided with pins 28 and 29. A spacing bar 3| is provided with keyhole slots 32 and .is placed over the pins 28 and 29. To keep the spacing barin place, the ends of the same will abut the ends of the bottom part 19 and will thereby keep the container properly spaced within the bottom Hi.

In Fig. 4, there is shown a modified form of container. This container is of cylindricalshape and has a screw cover 34. Thiscontainer is shown at 35. A bar 36 is connected to the container 35 and will, in the manner above-described, keep the container from sliding in the lunch basket. By having the spacing bar re movable from the container, it will not give trouble when the container is outside of the lunch basket.

a In Fig. 5, there is shown a modified'form of receptacle comprising a container body 38 having a rounded top portion 39. This top portion from the receptacle. The body-e8 and the-cover G5 are preferably formed of metal. vIt will be apparent that the receptacle 38 isof suchshape as to fit the main part [0. The spacing bar is connected to the metal cap 45 as indicated at 41.

It will be seen that there has been provided a simple construction for a Thermos container and also a simple means for keeping the container properly spaced in the lunch basket.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

I claim:

A scalable food container for fitting within a The body 38 has an 3 lunch basket and comprising a main vessel part, said main vessel part having a fiat bottom and a rounded top with an opening therein, a lining within the vessel and extending under the rounded top, an insulating cover fitting within the rounded top opening, a cover cap internally threaded and extending over the vessel and contacting the insulating cover, said vessel having threads receiving the threads of the cover cap, and an elongated spacing bar rigidly connected intermediate its length to the cover cap at a point located laterally thereon, said bar extending on each side beyond said cap in a plane substantially parallel with the flat bottom and normally engageable within the lunch basket to prevent the l sliding of the container therewithin.
